blank page with left column

[qiaog]

Not sure what caused it. After applying theme 'earth', besides the homepage the right blocks and the middle homepage content disappears and become invisible. The only visible items (homepage is good, for all the other pages) is the header, and left Blocks. If I change back to the defult theme, it seems no problem, but whenever I swith to earth, this problem happened. I checked out back office, and I did not see any error message.

As I would like to use 'earth' for my website, could you please help me to solve this issue. my test website is www.superpcworks.com/test1 if I am not clear, please have a look of this website and try to click some links, you should not what I am talking.

Help is greatly appreciated.
